Cresswell Towers anyone? Looking for cheap holiday in Northumberland

We want a cheap family holiday (DDs 4 and 1) in Nothumberland for October Half Term. I've been looking at Haven, but some of the reviews on here of Berwick aren't too favourable. Has anyone been to the Hoseasons in Northumberland. Cresswell Towers seems a reasonable price, but am worried it might be too cheap!
